SALT LAKE CITY (AP) -- Utah State University is rolling out an electric transit bus that's capable of being recharged wirelessly.
The school plans to showcase the first-of-its-kind technology in North Logan for the media Thursday.
Wireless power transfer has been used for years in some consumer devices and in factory power strips. Now it's ready for vehicles.
The Utah State bus gets a wireless boost from charging pads embedded in concrete. Engineers say electricity jumps the 10-inch air gap with little loss in energy. The system eliminates the need for plug-in charging and allows vehicles to use a smaller battery pack, which yields big weight savings.
